But one of the newest identified functions of the hormonal form of vitamin D, known as 1,25-D, is its role in determining how the body manages energy. In the American Journal of Clinical Nutrition, this past May, Michael B. Zemel laid out how 1,25-D helps the body decide whether the calories a person eats will be burned or stored as fat.

Earlier, his team at the University of Tennessee showed that calcium-rich products, especially milk and other dairy goods, foster weight loss (SN: 4/29/00, p. 277: Invalid Link Removed.
While investigating the mechanism behind this phenomenon, the Tennessee researchers discovered that fat cells contain receptors for 1,25-D. Furthermore, they found, the hormone actually promotes weight gain by sending calories into storage.
Zemel emphasizes that "it's not the dietary vitamin D that does this" but its hormonal form.

So, to keep that hormone at low to moderate concentrations, people must maintain adequate calcium intake

Although any calcium source will do—even supplement pills—Zemel's team has shown in a series of studies that "dairy products are more effective than plain calcium" at suppressing 1,25-D concentrations in fat cells. It turns out, he says, that "there are other components in dairy [foods] that act synergistically with the calcium to inhibit fat synthesis and augment fat breakdown."
 
Interesting. This seems like another example of keeping everything in balance for maximum health gains. If the balance gets disrupted, then unintended consequences.
